High-field study of UCo2Si2: magnetostriction at metamagnetic transition and influence of Fe substitution
Popis výsledku v původním jazyce
UCo2Si2 (tetragonal crystal structure) is antiferromagnet below T-N = 83 K with ferromagnetic basal-plane layers of U magnetic moments oriented parallel to the c axis. The layers are coupled in +-+- sequence along this axis. In fields of 45 T applied along the c axis, UCo2Si2 exhibits very sharp metamagnetic transition to ++- uncompensated antiferromagnetic state. The transition is accompanied by pronounced magnetostriction effects. The crystal expands along the c axis by 1 * 10(-4) and shrinks in the basal plane by 0.5 * 10(-4) (at 1.5 K) resulting in negligible volume effect. Between 20 K and 40 K the transition changes from the first-to the second-order type. The Fe doping in UCo2Si2 reduces T-N from 83 K to 80 K at x = 0.2 in U(Co1-xFex)(2)Si-2. Metamagnetic transition shifts to higher fields (from 45 T at x = 0-56 T for x = 0.2). Magnetization jump over the transition remains practically the same which is in agreement with uranium magnetic moment determined by neutron diffraction on crystal with x = 0.1 as 1.29 mu(B), i.e. only slightly lower than that in UCo2Si2.
