Spontaneous Magnetization of the xxz heisenberg spin 1 2 chain
Nuclear Physics, 1999Co-Authors: A G Izergin, N Kitanine, J M Maillet, V TerrasAbstract:Abstract Determinant representations of form factors are used to represent the Spontaneous Magnetization of the Heisenberg XXZ chain ( Δ > 1) on the finite lattice as the ratio of two determinants. In the thermodynamic limit (the lattice of infinite length), the Baxter formula is reproduced in the framework of Algebraic Bethe Ansatz. It is shown that the finite size corrections to the Baxter formula are exponentially small.

Spontaneous Magnetization under a pseudovector interaction between quarks in high density quark matter
arXiv: High Energy Physics - Phenomenology, 2018Co-Authors: Masatoshi Morimoto, Yasuhiko Tsue, J Da Providencia, Constanca Providencia, Masatoshi YamamuraAbstract:Spontaneous Magnetization and magnetic susceptibility originated from the pseudovector-type four-point interaction between quarks are calculated in quark matter with zero temperature and finite quark chemical potential by using the two-flavor Nambu-Jona-Lasinio model. It is shown that both the chiral condensate and spin polarized condensate coexist in a narrow region of the quark chemical potential. And then, it is also shown that, in this narrow region, the Spontaneous Magnetization appears. Also, the magnetic susceptibility due to quarks with the positive energy is evaluated in the spin polarized phase.

Spontaneous Magnetization in high density quark matter
arXiv: High Energy Physics - Phenomenology, 2015Co-Authors: Yasuhiko Tsue, J Da Providencia, Constanca Providencia, Masatoshi Yamamura, Henrik BohrAbstract:It is shown that the Spontaneous Magnetization occurs due to the anomalous magnetic moments of quarks in the high-density quark matter under the tensor-type four-point interaction. The spin polarized condensate for each flavor of quark appears at high baryon density, which leads to the Spontaneous Magnetization due to the anomalous magnetic moments of quarks. The implications to the strong magnetic field in the compact stars is discussed.

Pressure dependence of the Curie temperature and Spontaneous Magnetization of MnRhP
Journal of Magnetism and Magnetic Materials, 1998Co-Authors: K. Sato, N. Suzuki, Takeshi Kanomata, Hiroki Yamauchi, Hajime Yoshida, Tomoaki Kaneko, Y. Yamaguchi, T. Kamishima, T. GotoAbstract:Abstract The pressure effect on the Curie temperature T C and the Spontaneous Magnetization σ S at 4.2 K for MnRhP is investigated. T C increases linearly with pressure. The value of ∂ T C /∂ p is + 1.5 K/kbar. The Spontaneous Magnetization at 4.2 K is independent of pressure.

Pressure effect on Spontaneous Magnetization of Cr2Te3 and Cr5Te8
Journal of Magnetism and Magnetic Materials, 1998Co-Authors: Takeshi Kanomata, T. Goto, Y. Sugawara, K. Kamishima, Hiroyuki Mitamura, Satoru Ohta, Tomoaki KanekoAbstract:Abstract The pressure change of the Spontaneous Magnetization σ s at 4.2 K for Cr 2 Te 3 and Cr 5 Te 8 are measured by employing the subtraction magnetometer. The value of dσ s /dp for Cr 2 Te 3 is − 1.22emu/g kbar . For Cr 5 Te 8 , the pressure derivative of σ s is found to be almost zero.
