Microstrain induced deviation from Néel's 1/d behaviour: Size-dependent magnetization in Bi1-xCaxFe1-yTiyO3-delta nanoparticles
Pavana S. V. Mocherla, M. B. Sahana, Ehab Abdelhamid +7
Magnetization of antiferromagnetic nanoparticles is known to generally scale up inversely to their diameter (d) according to Néel's model. Here we report a deviation from this conv…
Influence of excitation frequency on Raman modes of In1-xGaxN thin films
A. Dixit, J. S. Thakur, V. M. Naik +1
Low energy optical modes of MBE-grown In1-xGaxN thin films with different values of x are investigated using Raman spectroscopy. We also studied the influence of Raman excitation f…
Oxygen vacancy enhanced room temperature ferromagnetism in Al-doped MgO nanoparticles
Debabrata Mishra, Balaji P. Mandal, Rupam Mukherjee +3
We have investigated the room temperature ferromagnetic order that develops in Al-substituted magnesium oxide, Mg(Al)O, nanoparticles with Al fractions of up to 5 at.%. All samples…
Ferromagnetism and spin polarized charge carriers in InO thin films
Raghava P. Panguluri, P. Kharel, C. Sudakar +6
We present evidence for spin polarized charge carriers in InO films. Both InO and Cr doped InO films exhibit room temperature ferromagnetism after vacuum an…
Electric field control of magnetic phase transitions in Ni3V2O8
P. Kharel, C. Sudakar, A. B. Harris +2
We report on the electric field control of magnetic phase transition temperatures in multiferroic Ni3V2O8 thin films. Using magnetization measurements, we find that the phase trans…
Positive and negative magnetocapacitance in magnetic nanoparticle systems
G. Lawes, R. Tackett, O. Masala +3
The dielectric properties of MnFeO and -FeO magnetic nanoparticles embedded in insulating matrices were investigated. The samples showed frequency dependent diel…
