Abstract
The YCo4B exhibits peculiar behavior of the magnetization curves related to the occurrence of a spinreorientation phenomenon at low temperature and of a first-order magnetization process.We present here a detailed investigation of the pressure dependence of this anomaly in awide temperature range 5–300 K. The evolution of the saturation magnetizationversus pressure is also presented on both sides of the spin reorientation transition.Studies were performed on single-crystalline samples under hydrostatic pressureup to 1 GPa pressure and in a magnetic field up to 5 T. Remarkable pressureeffects on the magnetocrystalline anisotropy parameter and on the critical field atwhich the first-order magnetization process occurs are analyzed and discussed.
