摘要: Abstract We report the first measurements of both linear and non-linear magnetic response a “re-entrant” system, (Pd+0.35 at% Fe)+5 at % Mn, in vicinity upper lower “candidate” transitions. The transition has been identified as well defined paramagnetic-ferromagnetic transition; associated critical exponents have found from field temperature dependence cross-over line above T c . An anomaly observed for time (located near which initial susceptibility falls abruptly). This takes form distinct, but clearly not divergent, peak coefficient H 2 term susceptibility. Such behaviour is strong indication re-entrant ferromagnetic-spin glass transition.
