“…In this work they observed ferromagnetic order in the sample with T C =329K. Although it is conclusively established that the high-temperature magnetic properties of the chalcopyrites doped with Mn are due to the MnAs inclusions [15,16], the reported change of the cell parameters in this work is quite reliable.…”

“…One material class that has been interesting to the optics community is II-IV-V2 chalcopyrite crystals due to their high nonlinearity, composition-tunable band gaps, wide transparency windows and high damage threshold [12][13][14][15]. Chalcopyrite crystals have been explored for electromagnetic (EM) screening, spintronic [16,17], and photovoltaic applications [18], making them good as optical and optoelectronic materials. Large-area chalcopyrite crystal growth offers the opportunity to produce devices [19][20][21][22][23], especially frequency converters.…”

Terahertz time-domain spectroscopy is employed to investigate temperaturedependent properties of bulk chalcopyrite crystals (CdGeP2, ZnGeP2 and CdSiP2). The complex spectra provide the refraction and absorption as a function of temperature, from which electron-phonon coupling and average phonon energies are extracted and linked to the mechanics of the A-and B-site cations. Also, AC conductivity spectra provide carrier densities and electron scattering times, the temperature dependence of which is associated with unintentional shallow dopants. Temperature dependence of the scattering time are converted into carrier mobility and modeled with microscopic transport mechanisms such as polar optical phonon, acoustic phonons, deformation potential, ionized impurity and dislocation scattering. Hence, analysis links the THz optical and electronic properties to relate microscopic carrier transport and carrier-lattice interactions.

An analytical review devoted to the physicochemical principles of the synthesis of granular structures in semiconductor-ferromagnet systems is represented. In these systems, as semiconductors, compounds are A II B IV C V 2 , A III C V , A II 2 C V 3 and A II C V 2 and manganese compounds (MnP, MnAs and MnSb) as ferromagnets. It is shown that in magnetostransmitter devices magnetogranular structures are an alternative to superlattices, and the effects of GMR and TMR are also possible. Advantages of magneto-granular structures are considered, such as: less labor-intensive methods of production, milder requirements for the dimension of a ferromagnet and a nonmagnet, the possibility of forming a stable interface, soft requirements to the thickness of layers than in the case of superlattices, etc. It is shown that, due to the high mobility of charge carriers, the use of semiconductors as a matrix is more preferable than metals or dielectrics. The basic principles for the creation of granular structures with high values of magnetoresistance based on eutectic-type systems are formulated. During the crystallization of the eutectic, the simultaneous crystallization of all the phases that make up the eutectic takes place, leading to the formation of a specific fine-dispersed structure. The use of ultrahigh supersaturations leads to significant supercooling, which contributes to metastable crystallization. This causes a synergistic effect that stimulates nanostructuring, and promotes the creation of granular structures. The results of investigations of semiconductor-ferromagnet systems are presented and the possibility of obtaining magnetogranular structures with high magnetoresistance in them is shown.
