ABSTRACT
In this research, a low temperature in-field 57Fe Mössbauer spectroscopy is used for investigation of anomalous magnetic properties of MnZn nanoferrite. Based on Mössbauer spectroscopy results, the reduced saturation magnetization of MnZn nanoferrite in respect to that of bulk sample is due to nonequilibrium cation distribution and spin disorder. The enhanced Curie temperature of MnZn nanoferrite in respect to that of bulk sample can be attributed to the strengthening of the (A)-O-[B] superexchange interactions due to an increase of the magnetic ion concentration in the (A) site.

    The intermetallic compound CeRh2Si2 has been investigated by means of perturbed γ-γ angular correlation (PAC) spectroscopy using 111In(111Cd) and 140La(140Ce) probe nuclei. Measurements with 111Cd were carried out in the temperature range of 8-295 K. The results showed a highly distributed...

    We theoretically show that the use of the hyperfine interaction together with a static electric field leads to ultrafast nuclear spin polarization. The idea is specifically applied to the isotopes of alkaline-earth atoms such as 27Mg (I = 1/2) and 37 Ca (I = 3/2), and we find that spin...
