ATOMIC AND MAGNETIC SRO IN Fe-Mn-Si ALLOYS
نویسندگان
چکیده
Neutron diffuse scattering and saturation magnetization experiments have been made on single crystals specimens of Fe3-,MnCSi with c = 0.164 and 0.284 at room temperature. Atomic clustering of Mn atoms on the B sublattice has been revealed. A model of magnetic moment distribution around Mn impurities has been developed and fitted to the experimental magnetic diffuse cross sections. RRsults obtained lead to the conclusion that the magnetic moment on the Mn atom is about 0.6 p~ at room temperature, and is very likely to be strongly temperature dependent.

Antiferromagnetism in Ru2MnZ (Z=Sn, Sb, Ge, Si) full Heusler alloys: effects of magnetic frustration and chemical disorder
We present systematic theoretical investigations to explore the microscopic mechanisms leading to the formation of antiferromagnetism in Ru2MnZ (Z= Sn,Sb,Ge,Si) full Heusler alloys. Our study is based on first-principles calculations of inter-atomic Mn-Mn exchange interactions to set up a suitable Heisenberg spin-model and on subsequent Monte-Carlo simulations of the magnetic properties at fini...

This is well known that amorphous state is metastable. Metastability of amorphous or glassy metal alloys offers the possibility of phase separation diffusion of various species and structural relaxation even though the alloys remains amorphous when they are annealed at temperature well below the crystallization temperature. All these changes have effect on the intrinsic magnetic properties such...

By means of self-consistent semi-empirical LCAO calculations we study the itinerant magnetism of (Fe 0.65 Ni 0.35) 1−y Mn y alloys for y between 0 and 0.22 at T = 0 K, neglecting only the transverse spin components. We find that the magnetic behaviour is quite complicated on a local scale. In addition to ferromagnetic behaviour, also metastable spin-glass-like configurations are found. In the s...

Rock powder of dolomite samples from the Renison mine area of Tasmania, Australia were analyzed by electron paramagnentic resonance spectroscopy (EPR), Atomic Absorption and Mass Spectrometer to identify alteration related to mineralisation. The least-altered dolomite samples, which are not effected by circulation of diagenetic and hydrothermal fluids are characterised by low Mn and Fe and ...

The magnetic and structural properties of an Si-rich grade FINEMET alloy with a composition of Fe73.5Si16.1B6.4Nb2.9Cu1.1 in at% [Fe82.7Si9.1B1.4Nb5.4Cu1.4 (wt%)] were investigated after primary and secondary crystallization of ribbon samples. Optimally annealed ribbons exhibited a homogeneous microstructure composed of B7 nm DO3 nanocrystals surrounded by the retained amorphous phase. This is ...
