Effect of local structural distortions on magnetostructural transformation in MnSnC
E. T. Dias, K. R. Priolkar, A. Das +4
In this paper we attempt to understand the different nature of first order magnetic transformation in MnSnC as compared to that in MnGaC. The transformation in MnSnC is…
Phase formation characteristics and magnetic properties of bulk Ni2MnGe Heusler alloy
U. Adem, I. Dincer, S. Akturk +2
We have systemically studied the effects of annealing temperature and alloy composition on the structural and magnetic properties of bulk NiMnGe and NiMnGe He…
Anomalous vibrational effects in non-magnetic and magnetic Heusler alloys
A. T. Zayak, P. Entel, K. M. Rabe +2
First-principles calculations are used in order to investigate phonon anomalies in non-magnetic and magnetic Heusler alloys. Phonon dispersions for several systems in their cubic L…
Residual stress induced stabilization of martensite phase and its effect on the magneto-structural transition in Mn rich Ni-Mn-In/Ga magnetic shape memory alloys
Sanjay Singh, Pallavi Kushwaha, F. Sceibel +5
The irreversibility of the martensite transition in magnetic shape memory alloys (MSMAs) with respect to external magnetic field is one of the biggest challenges that limits their…
Effect of composition on magnetocaloric properties of MnGaSnC
E. T. Dias, K. R. Priolkar, O. Cakir +2
A study investigating the effect of Sn substitution on the magnetocaloric properties of MnGaSnC compounds reveals that nature of the MCE has a strong de…
Dynamics of the magnetoelastic phase transition and adiabatic temperature change in Mn1.3Fe0.7P0.5Si0.55
M. Fries, T. Gottschall, F. Scheibel +7
The adiabatic temperature change DTad of a Mn1.3Fe0.7P0.5Si0.55 Fe2P-type alloy was measured under different magnetic field-sweep rates from 0.93 Ts-1 to 2870 Ts-1. We find a field…
Importance of site occupancy and absence of strain glassy phase in NiFeMnIn
R. Nevgi, Gangadhar Das, M. Acet +1
Martensitic transition temperature steadily decreases in NiFeMnIn and is completely suppressed at = 0.2. Despite suppression of martensitic transi…
Magnetovolume instabilities in the pressure dependence of the K-edge circular dichroism of Fe3C Invar particles
E. Duman, M. Acet, E. F. Wassermann +4
The p-electrons of carbon in the interstitial compound Fe3C hybridize with the Fe d-band and enhance the valence electron concentration of Fe from 8 to 8.67. At this concentration,…
