Electrically detected paramagnetic resonance in Ag-paint coated DPPH
Lee Yong Heng, Ushnish Chaudhuri, Ramanathan Mahendiran
We describe a simple experimental method to detect electron paramagnetic resonance (EPR) in polycrystalline 2,2-diphenyl-1-picrylhydrazyl (DPPH) sample, the standard g-marker for E…

Paramagnetic resonance in La2NiMnO6 probed by impedance and lock-in detection techniques
Ushnish Chaudhuri, Debendra Prasad Panda, A. Sundaresan +1
We report the detection of paramagnetic resonance in the double perovskite La2NiMnO6 at room temperature for microwave magnetic fields with frequencies, f = 1 GHz to 5 GHz, using t…

Microwave magnetoabsorption in R0.6Sr0.4MnO3 (R = Pr and Nd)
A. Chanda, U. Chaudhuri, R. Mahendiran
We report microwave magnetoabsorption (P) at room temperature in R0.6Sr0.4MnO3 (R = Pr and Nd) samples. P as a function of dc magnetic field (-2.5 kOe to +2.5 kOe) was measured for…
