The Magnetic Resonance Force Microscope (MRFM) presents the opportunity for a magnetic resonance imaging probe with ultra-high, potentially atomic-scale, resolution. The successful application of this technique in detection of nuclear magnetic, electron-spin and ferromagnetic resonance (FMR) highlights its significant potential. We discuss the capabilities of the MRFM with particular emphasis o...

A crucial remaining challenge in the development of the magnetic resonance force microscope (MRFM) is to place the magnetic probe on the mechanical resonator. Here we address the problem of spurious detector response arising from interactions between the magnetic tip and various external applied elds. Ferromagnetic resonance experiments on a microscopic, thin-lm yttrium iron garnet crystal moun...

The four-component Hantzsch condensation reaction of dimedone, ethyl acetoacetate, ammonium acetate, and various aromatic and aliphatic aldehydes in the presence of catalytic amount of a magnetic nanoparticle-supported tribromide, as a green catalyst, under solvent‐free conditions at 80 °C affords functionalized 5-oxo-hexahydroquinolines in good to excellent yields. The magnetic Fe3O...

In this research nanoparticles of Ni0.55Zn0.35Cu0.1Fe2O4 were synthesized by sol–gel auto-combustion method. Changes in phase constituents, microstructure and magnetic properties as a result of Zn and Cu additions were evaluated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Vibration Sample Magnetometer (VSM) techniques. XRD results show that the doped sam...

We consider various methods and techniques for measuring electron magnetization susceptibility, which are used in experimental condensed matter physics. The list of considered macroscopic measurements includes magnetomechanic, electromagnetic, modulation-type, also thermodynamic based on the chemical potential variation. local magnetic spin Hall effects NV-centers. Several scanning probe magnet...

The quantitative measurement of the magnetization of individual magnetic nanoparticles (MNPs) using magnetic force microscopy (MFM) is described. Quantitative measurement is realized by calibration of the MFM signal using an MNP reference sample with traceably determined magnetization. A resolution of the magnetic moment of the order of 10(-18) A m(2) under ambient conditions is demonstrated, w...

We report achieving enhanced nuclear magnetization in a magnetic resonance force microscope experiment at 0.6 tesla and 4.2 kelvin using the dynamic nuclear polarization (DNP) effect. In our experiments a microwire coplanar waveguide delivered radiowaves to excite nuclear spins and microwaves to excite electron spins in a 250 nm thick nitroxide-doped polystyrene sample. Both electron and proton...
