Two porous glassy carbon-based samples doped with Au and Co were investigated. The magnetization study as well as measurements of the nonlinear longitudinal response to a weak ac field (NLR) and electron magnetic resonance give evidences for a presen

The temperature dependence of the magnetic susceptibility in Co 0.5 Al 0.5− x Pd x when x is increased from 0.015 to 0.11 is similar to that of Co 0.5 Al 0.5− x Co x and demonstrates subsequently cluster-glass, mictomagnetic and re-entrant ferrom
