Magnetic and Hyperfine interactions in HoFe1-xCrxO3 compounds
Ganesh Kotnana, V. Raghavendra Reddy, S. Narayana Jammalamadaka
We report on the magnetic and Mossbauer properties of polycrystalline HoFe1-xCrxO3 compounds. Magnetization data reveals the continuous tailoring of magnetic transition due to weak…
Enhanced spin reorientation temperature and origin of magnetocapacitance in HoFeO3
Ganesh Kotnana, S. Narayana Jammalamadaka
We report on the increase in the spin reorientation temperature in HoFe0.5Cr0.5O3 compound by isovalent substitution Cr3+ at the Fe-site and the magnetocapacitance in the HoFeO3 co…
Band gap tuning and orbital mediated electron phonon coupling in
Ganesh Kotnana, S. Narayana Jammalamadaka
We report on the evidenced orbital mediated electron phonon coupling and band gap tuning in HoFe1-xCrxO3 compounds. From the room temperature Raman scattering, it is apparent that…
Martensite-like transition and spin-glass behavior in nanocrystalline Pr0.5Ca0.5MnO3
S. Narayana Jammalamadaka, S. S. Rao, J. Vanacken +3
We report on isothermal pulsed (20 ms) field magnetization, temperature dependent AC - susceptibility, and the static low magnetic field measurements carried out on 10 nm sized Pr0…
Magnetic Anomalies in a New Manganocuprate Gd3Ba2Mn2Cu2O12
Sudhindra Rayaprol, Kiran Singh, N. K. Gaur +3
The manganocuprate compound Gd3Ba2Mn2Cu2O12 (Gd-3222) has been synthesized by conventional solid state reaction method and its magnetic behavior has been studied by dc and ac magne…
Room temperature soft ferromagnetism in the nanocrystalline form of YCo2 - a well-known bulk Pauli paramagnet
S. Narayana Jammalamadaka, E. V. Sampathkumaran, V. Satya Narayana Murthy +1
The Laves phase compound, YCo2, is a well-known exchange-enahnced Pauli paramagnet. We report here that, in the nanocrystalline form, this compound interestingly is an itinerant fe…
