Simultaneous optical trapping and magnetic micromanipulation of ferromagnetic iron-doped upconversion microparticles in six degrees of freedom
Gokul Nalupurackal, Gunaseelan M, Muruga Lokesh +9
Optical trapping of magnetic Fe-oxide particles is notoriously difficult due to their high refractive indices, not to mention high absorptivity at the trapping infra-red wavelength…
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…
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…
Significant enhancement of room temperature ferromagnetism in surfactant coated polycrystalline Mn doped ZnO particles
O. D. Jayakumar, I. K. Gopalakrishnan, C. Sudakar +2
We report a surfactant assisted synthesis of Mn doped ZnO polycrystalline samples showing robust room temperature ferromagnetism as characterized by X-ray diffraction analysis, Tra…
Magnetic properties of Hydrogenated Li and Co doped ZnO nanoparticles
O. D. Jayakumar, I. K. Gopalakrishnan, K. Shasikala +1
The effect of hydrogenation on magnetic properties of Zn0.85Co0.05Li0.10O nanoparticles is presented. It was found that the sample hydrided at room temperature (RT) showed weak fer…
