Dynamic Radio-Frequency Transverse Susceptibility in Magnetic Nanoparticle Systems
L. Spinu, H. Srikanth, E. E. Carpenter +1
A novel resonant method based on a tunnel-diode oscillator (TDO) is used to study the dynamic transverse susceptibility in a Fe nanoparticle system. The magnetic system consists of…
Magneto-impedance of glass-coated Fe-Ni-Cu microwires
J. Wiggins, H. Srikanth, K. -Y. Wang +2
The magneto-impedance (MI) of glass-coated Fe-Ni-Cu microwires was investigated for longitudinal radio-frequency (RF) currents up to a frequency of 200 MHz using an RF lock-in ampl…
Dynamic transverse susceptibility in Au-Fe-Au "nano-onions"
H. Srikanth, E. E. Carpenter, C. J. O'Connor
A precision radio-frequency (RF) transverse modulation technique based on a resonant tunnel diode oscillator (TDO) has been used to study the dynamic susceptibility in novel ring-s…
Radio-frequency impedance measurements using a tunnel-diode oscillator (TDO) technique
H. Srikanth, J. Wiggins, H. Rees
A resonant method based on a tunnel-diode oscillator (TDO) for precision measurements of relative impedance changes in materials, is described. The system consists of an effective…
