Magnetization study on the ising ferromagnet URhGe with high-precision angle-resolved magnetic field near the hard axis

Popis výsledku v původním jazyce

Dc magnetization measurements have been performed on the orthorhombic Ising ferromagnet URhGe with high-precision control of the magnetic field direction near the hard b axis. The ferromagnetic moment of this compound, which aligns along the c axis in zero field, is known to exhibit a reorientation transition in the b-axis magnetic field Hb. We observed a clear first-order reorientation transition with a small hysteresis, and estimated that the tricritical point TCP is located above 4 K at least, at 0Hb~10.5 T and the wing quantum critical points exist at 0(Hb, Hc) ~ (13.5 T, 1 T). We have also measured the longitudinal magnetostriction and thermal expansion of URhGe with H along the b axis, and observed that the lattice shrinks along the b axis upon the transition. The magnetization and the thermal expansion data indicate the presence of a characteristic temperature ~1 K.
