From spin splitting to projected mass in altermagnetic Chern matter
Gyanti Prakash Moharana
Altermagnetic spin splitting alone does not define Chern matter. The relevant object is the exchange mass projected onto Hall-active surface, valley, orbital or interface sectors.…
Griffiths-like phase, spin-phonon coupling, and exchange-bias in the disordered double perovskite GdSrCoMnO
Gyanti Prakash Moharana, Diptikanta Swain, Hanuma Kumar Dara +2
We report structural, magnetic, and Raman studies of the disordered double perovskite GdSrCoMnO~(GSCM). DC magnetization shows a ferromagnetic transition at $T_{C} \approx 15…
F+ Center Exchange Mechanism and Magneto Crystalline Anisotropy in Ni doped 3C-SiC
Gyanti Prakash Moharana, Rahul Kothari, S. K. Singh +2
We report the experimental evidence in support of room temperature ferromagnetism in Ni doped 3C-SiC. Curie temperature is found to be > 350 K. Temperature dependent Electron param…
Interplay of Bound Magnetic Polaron and p-d exchange interaction in Co-doped 3C-SiC
Gyanti Prakash Moharana, Rahul Kothari, S. K. Singh +2
Bound Magnetic Polarons (BMP) have been proposed to play an important role in doped wide band gap semiconductors. We report the experimental evidence supporting polaronic magnetism…
Role of Spin, Phonon and Plasmon Dynamics on Ferromagnetism in Cr doped 3C-SiC
Gyanti Prakash Moharana, Rahul Kothari, S. K. Singh +1
The defect induced magnetism has initiated a lot of interest in field of spintronics. In this regard, SiC is a promising material because of its unique properties under extreme con…
