Magnetic Susceptibility of the QCD vacuum
Physics Letters B, 2005Co-Authors: Hyun-chul Kim, M. Musakhanov, M. SiddikovAbstract:Abstract We investigate the Magnetic Susceptibility of the QCD vacuum, based on the instanton vacuum. Starting from the instanton liquid model for the instanton vacuum, we derive the light-quark partition function Z [ V , T , m ˆ ] in the presence of the current quark mass m ˆ as well as the external Abelian vector and tensor fields. We calculate a two-point correlation function relevant for the Magnetic Susceptibility and derive it beyond the chiral limit. We obtain for the different flavors the following Magnetic Susceptibility: χ u , d 〈 i ψ u , d † ψ u , d 〉 0 ∼ 40 – 45 MeV , while χ s 〈 i ψ s † ψ s 〉 0 ≃ 6 – 10 MeV with the quark condensate 〈 i ψ † ψ 〉 0 .

Physics Letters B, 2005Co-Authors: Hyun-chul Kim, M. Musakhanov, M. SiddikovAbstract:We investigate the Magnetic Susceptibility of the QCD vacuum, based on the instanton vacuum. Starting from the instanton liquid model for the instanton vacuum, we derive the light-quark partition function $Z[V,T,\hat{m}]$ in the presence of the current quark mass $\hat{m}$ as well as the external Abelian vector and tensor fields. We calculate a two-point correlation function relevant for the Magnetic Susceptibility and derive it beyond the chiral limit. We obtain for the different flavors the following Magnetic Susceptibility: $\chi_{u,d}< i\psi_{u,d}^\dagger \psi_{u,d}>_0 \sim 40\sim45 {\rm MeV}$, while $\chi_{s}< i\psi_s^\dagger \psi_s >_0 \simeq 6\sim 10 {\rm MeV}$ with the quark condensate $_0$.Comment: 13 pages, 2 figure

Magnetic Susceptibility measurement of insoluble solids by nmr Magnetic Susceptibility of bone
Magnetic Resonance in Medicine, 1997Co-Authors: Jeffrey A Hopkins, Felix W WehrliAbstract:Measurements of the volume Magnetic Susceptibility of solids using the classical Gouy balance approach are hampered by variations in apparent density of the packed powder. In this paper a quantitative NMR measurement of the volume Magnetic Susceptibility of powdered solids is described and the volume Susceptibility of bone is reported. The technique is based on the measurement of changes in incremental linewidth (1/πT2′) induced in a marker fluid whose Susceptibility can be predictably modified by changing the composition, such as by addition of a soluble diaMagnetic compound. The spectroscopic linewidth of the marker fluid is determined by the Susceptibility difference between the fluid and the suspended solid. Changes in the linewidth are accompanied by bulk Magnetic Susceptibility induced frequency shifts in the fluid resonance. Correlating the two dependencies allows measurement of the absolute volume Susceptibility of the solid. The Susceptibility of bovine rib bone was found to be −0.90 ± 0.02 × − 10−6 (CGS) confirming previous estimates which suggested bone to be more diaMagnetic than the marrow constituents. Knowledge of the Susceptibility of bone is relevant in view of the growing interest in MRI osteodensitometric techniques.

The Magnetic Susceptibility and Structure of BaUO3
Journal of Solid State Chemistry, 1993Co-Authors: Yukio HinatsuAbstract:Barium uranate, BaUO3.023, was prepared and its Magnetic Susceptibility was measured in the temperature range between 4.2 K and room temperature. X-ray diffraction analysis showed it was an ideal cubic perovskite. From the Magnetic Susceptibility measurements, it was found that oxygen stoichiometric BaUO3 shows the temperature-independent paramagnetism over the temperature range from 4.2 K to room temperature. which is in accord with the octahedral oxygen coordination around the U4+ ion. The Susceptibility of BaU1-yThyO3 was also measured.

Magnetic Susceptibility of LiUO3
Journal of Solid State Chemistry, 1992Co-Authors: Yukio Hinatsu, Takeo Fujino, Norman M. EdelsteinAbstract:Abstract LiUO3 was prepared, and its Magnetic Susceptibility was measured in the 4.2–300 K temperature range. Magnetic transition occurred at 16.9 K, and below this temperature large field dependence of the Magnetic Susceptibility was observed. The crystal field parameters of LiUO3 were determined from the optical absorption spectrum of U5+ doped in LiNbO3. The Susceptibility and the g-value of electron paraMagnetic resonance were calculated and compared with the experimental results.
