Resonance-based Detection of Magnetic Nanoparticles and Microbeads Using Nanopatterned Ferromagnets
Manu Sushruth, Junjia Ding, Jeremy Duczynski +7
Biosensing with ferromagnet-based magnetoresistive devices has been dominated by electrical detection of particle-induced changes to the devices' static magnetic configuration. The…
Sensing magnetic nanoparticles using nano-confined ferromagnetic resonances in a magnonic crystal
Peter Metaxas, Manu Sushruth, Ryan Begley +8
We demonstrate the use of the magnetic-field-dependence of highly spatially confined, GHz-frequency ferromagnetic resonances in a ferromagnetic nanostructure for the detection of a…
Temperature dependence of Magnetic properties in Nanocrystalline copper ferrite thin films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
The copper ferrite thin films have been deposited by RF sputtering at a 50W rf power. The As-deposited films are annealed in air at C and then slow cooled. The As-depo…
The High Field Magnetization in the RF Sputter Deposited Copper Ferrite Thin Films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
Copper ferrite thin films were deposited on amorphous quartz substrates. The as deposited films were annealed in air and either quenched or slow cooled. Magnetization studies were…
Superparamagnetism in Nanocrystalline Copper Ferrite Thin Films
P. D. Kulkarni, R. P. R. C. Aiyar, Shiva Prasad +6
The rf sputtered copper ferrite films contain nanocrystalline grains. In these films, the magnetization does not saturate even in high magnetic fields. This phenomenon of high fiel…
