“…A superconducting quantum interference device (SQUID, Quantum design, MPMS XL), and a micro-Raman spectrometer (Renishaw system 1000) with 532 nm incident photons from a diode-pump solid state laser operated at a maximum power of 3.5 mW were used to determine the antiferromagnetic anisotropy and spin-wave waveguide of the 1D NiO nanorods, respectively. The application of the optical magnonics on the 1D NiO nanorods was evaluated by using a magneto-optical Faraday effect (MOFE) magnetometer [40][41][42] (homemade) using a polarized He-Ne laser beam of 633 nm.…”

The two-magnon (2M) spin waves with a magnon frequency of 43 THz, generated by a polarized laser, were first observed in one-dimensional (1D) NiO nanorods. The 1D NiO nanorods of ∼700 nm length, which have perfectly in-plane antiferromagnetic spins lying on the (200) and (100) faces, are the smallest spin-wave waveguides. Due to the magneto-optical Faraday effect (MOFE), the significant change in the Faraday intensity can show the 2M information in the NiO nanorods. There are only two 2M-on and 2M-off states at various applied alternating-current magnetic fields and laser-incident angles, which make the 1D NiO nanorods excellent optical nanomagnonics.

“…The magnetic domains in a magnetic film are separated by domain walls with approximate thicknesses of several hundred atomic layers. In the research into the physical characteristics of magnetic films, the magneto‐optic Kerr effect (MOKE) (Arora et al, ; Kim et al, ; Pathak & Sharma, ; Su, ; Su, et al, ; Westphalen et al, ) is a well‐established and commonly used analytical tool. The MOKE primarily measures the magnetic hysteresis loop of a magnetic film.…”

Perpendicular or parallel magnetic fields are used to magnetize the tips used in magnetic force microscopy (MFM). In this process, perpendicular or parallel magnetic dipole moments are produced on the tip plane, thus leading to the formation of polar magnetized tips (PM-tips) or longitudinally magnetized tips (LM-tips), respectively. The resolution of an MFM image of a magneto-optic disk is used for calibration of these tips, and the saturated magnetic fields of the PM- and LM-tips are found to be 2720 Oe and 680 Oe, respectively. Because both tips can simultaneously magnetize the sample during the scanning process when measuring a Co thin film, clear MFM images are captured, which enable the identification of magnetizable regions and the distribution of the magnetic domains on the sample surface. These results will be useful for improving the manufacturing processes required for soft nano-magnetic film production.
