概要

• 論文の詳細を見る

• The spin-wave dispersion relation of Cr-modified Mn_2Sb was measured by inelastic neutron scattering through the exchange inversion temperature. A two-dimensional magnetic character perpendicular to c-axis is obvious in the dispersion curves. The interplane exchange interaction changes noticeably with temperature and is well described by a quadratic function of the interplane distance. The elastic constant estimated according to Jarrett's theory is in fair agreement with that obtained from sound velocity. The scocnd order exchange striction is found to be large; and its relation to the thermal expansion coefficient is discussed.
