Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

The giant magnetoresistance-spin valve (GMR-SV) multilayer of NiFe/Cu/NiFe/Ta based on antiferromagnetic NiO was fabricated by using a sputtering deposition system. The thin multilayer with a width of the thin film passing through the 4-terminal was formed differently. The magnetic properties obtained from the major and the minor magnetoresistance curves measured at room temperature (RT) and at 77 K were investigated for thin films with four different widths. The exchange coupling field (H$ _{\text{ex}}$), the coercivity (H$ _{\text{c}}$), and the magnetoresistance ratio (MR) of the NiO GMR-SV multilayer with a 4 mm width were 30 Oe, 35 Oe, and 3.3% at room temperature and 190 Oe, 200 Oe, and 7.3% at 77 K. The value of H$ _{\text{ex}}$ and H$ _{\text{c}}$ for the NiFe free layer were constant at RT and 77 K, as the width of the multilayer decreased to 0.5 mm, and the MR ratio decreased linearly to 2.9% at RT and 6.4% at 77 k. Based on these properties, we proposed a self-driving spin-device(2SD) that can be developed as a hybrid-type multilayer composed of high-Tc superconductor YBCO film and NiO spin valve film.

Magnetic nanoparticles (MNPs) and magnetic beads (MBs) were distinguished from each other and mixed with red blood cells (RBCs) and physiological saline solution (PBS). The dependence of the resistance on the structure of and the existence of an external magnetic field were investigated. The MNPs had a diameter of 460~nm in which the carboxyl group ($-$COOH) was attached to the core Fe, and the MBs had an average diameter of about 1~$\mu$m with the Si$-$OH group in the core Fe$ _{3}$O$ _{4}$. Four different types of RBCs combined with 7 to 9 MBs were found to be located at the center and the edge with normal round and abnormal RBC membranes. We observed the appearance of cluster flow in the shape of a swirling cluster when we used a permanent magnet with large amounts of MNPs and MBs combined with RBCs contained in PBS. The resistance values ​​measured for 30~min in a 2.5~cc PBS solution containing 0.5~cc of a solution containing MNPs and MBs showed a different rates of increase that depended on the influence of the external magnetic field. On the other hand, the magnetoresistance ratio (MR) of MBs evenly mixed in deionized distilled water (ddH$ _{2}$O) was changed to about $-$36\% in range of $\pm$1200 Oe.
