frequency dependency of magnetic susceptibility in sp magnetite grains
using a magnetic property measurement system (mpms), we measure magnetic susceptibility continuously at frequencies from 0 to 1000 hz for three different superparamagnetic (sp) grain sizes of magnetite (5nm, 7 nm and 10 nm) suspended in hydrocarbons (ferrofluids). our results confirm non-zero values of frequency-dependent susceptibility in the fine tail of nano-sized grains and provide new empi...
متن کاملEffect of Low-Frequency AC Magnetic Susceptibility and Magnetic Properties of CoFeB/MgO/CoFeB Magnetic Tunnel Junctions
In this investigation, the low-frequency alternate-current (AC) magnetic susceptibility (χac) and hysteresis loop of various MgO thickness in CoFeB/MgO/CoFeB magnetic tunneling junction (MTJ) determined coercivity (Hc) and magnetization (Ms) and correlated that with χac maxima. The multilayer films were sputtered onto glass substrates and the thickness of intermediate barrier MgO layer was vari...
متن کاملFormulation and Evaluation of Magnetic Microspheres Of Cytarabine
Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...
متن کاملMagnetic Properties of Composite Hematite/Yttrium Oxide Colloidal Particles.
The effect of the shell thickness and density on the magnetic properties of composite colloidal particles consisting of a hematite (alpha-Fe(2)O(3)) core and an yttrium oxide (Y(2)O(3)) layer is described. Pure iron oxide colloidal spheres show two clearly different trends of variation of their magnetic susceptibility, chi(m), with temperature. Below T(M) approximately 220 K, chi(m) shows a sli...
