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...

Impedance and Modulus Spectroscopy Characterizations of CuO-Added K$_{0.5}$Na$_{0.5}$NbO$_3$ Single Crystals
Chan-Ku LEE*
Division of Mathematics, Science, and Computers, Kyungnam University, Changwon 51767, Korea
Lead-free piezoelectric single crystals of K$_{0.5}$Na$_{0.5}$NbO$_3$(KNN)-$x$CuO ($x$ = 0.01, 0.02, 0.03, 0.04) were grown by using the Czochralski method. In the present study, the effect of the added CuO on the electrical behavior (impedance, modules, and conductivity relaxation mechanisms) of the KNN single crystals were carried out by using a complex impedance spectroscopy technique in the frequency range from 100 Hz to 5 MHz at temperatures from 30 to 650$^\circ$C. The Cole-Cole plots exhibited two impedance semicircles, one associated with the bulk and the other with the twin boundaries in the crystalline layers, and confirmed the presence of non-Debye-type relaxation. The scaling behavior of modulus ($M^{\prime\prime}$) spectrum confirmed that the relaxation dynamics was independent of both the dopant and the temperature. The relaxation nature of the modulus was governed by the hopping of oxygen-ion vacancies in electrical transport processes. The frequency dependence of the ac conductivity data followed a power law $\sigma_{ac}$ = $A\omega^s$ with $0.06 \leq s \leq 1$. The thermal activation energies ($E_a$) for the conduction of charge carriers in the cubic phase were calculated as 0.91 eV for $x$ = 0.01 and 0.84 eV for $x$ = 0.04.

Study on the Elastic Properties and the Phase Transition Behavior of Condensed Matter by Using Brillouin Light Scattering Spectroscopy
Jae-Hyeon KO*
Department of Physics, Hallym University, Chuncheon 24252, Korea
Brillouin spectroscopy is one of the inelastic laser-light scattering spectroscopies and is used to probe long-wavelength low-energy excitation processes in the characteristic frequency range of a few tens of gigahertz. Based on this technique, the velocities of acoustic waves in amorphous materials, such as polymers and liquids, and the energies and the elastic constants of acoustic phonon modes in crystals can be determined accurately. The elastic property is one of the fundamental physical properties in condensed matter, and it is sensitive to phase transitions and to changes in structure or composition. In this paper, we review the principles and the measurement methods of Brillouin spectroscopy and their main applications. Especially, we discuss property data and related physics obtainable from Brillouin spectroscopy by investigating several application examples, such as perovskite-structured oxide materials showing ferroelectricity or a relaxor state and amorphous materials including polymers.
