57Fe Mössbauer spectroscopic study of the spin-glass transitions in the mixed spinel series Mg0.9+xFe2(1-x)Ni0.1Ti0.1O4
Magnetically diluted materials with spinel structure can fulfil the conditions for spin-glass behaviour. On the other hand, such spinels were also reported to exhibit a superparamagnetic behaviour due to the existence of small magnetic clusters in the spinel lattice. In order to gain some insight …

Magnetic resonance in amorphous iron-nickel alloys
… Fe8Ni72P20 and Fe10Ni70P20 show paramagnetic to spin-glass transitions, while Fe16N~4P20 shows paramagnetic to ferromagnetic and ferromagnetic to spin-glass transitions. The lineshape, at both frequencies, undergoes a progressive distortion as the temperature is reduced. We use an improved …

Computational studies of thermal and quantum phase transitions approached through non-equilibrium quenching
Phase transitions and their associated critical phenomena are of fundamental importance and play a crucial role in the development of statistical physics for both classical and quantum systems. Phase transitions embody diverse aspects of physics and also have numerous applications outside physics, …
