Using a suite of spectroscopic techniques, both in equilibrium and out-of-equilibrium settings, several important findings have been made. In a family of transition metal thiophosphates, a novel bound state resulting from electronic transitions between d-orbitals and Raman-active phonons was observed in NiPS3, using femtosecond transient absorption spectroscopy. Furthermore, this phonon symmetry was employed to identify a new magnetostrictive effect in FePS3 through coherent phonon spectroscopy. These and other observations point to strong interactions between spin and lattice degrees of freedom in this system. This coupling has been harnessed to actively control the magnetic structure. Specifically, intense, tailored terahertz pulses were used to displace the lattice along particular phonon directions, inducing a new magnetic order characterized by net magnetization. This effect is notably more efficient and exhibits an increasingly longer lifetime near the phase transition point, highlighting the key role played by critical fluctuations. Finally, second harmonic generation, linear dichroism, and Raman spectroscopy were employed to discover a new type-II multiferroic phase that persists down to the atomic monolayer limit in NiI2. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5061 606 $aMagnetism 606 $aSpectrum analysis 606 $aPhotonics 606 $aCondensed matter 606 $aMaterials$xAnalysis 606 $aQuantum statistics 606 $aMagnetism 606 $aSpectroscopy 606 $aUltrafast Photonics 606 $aPhase Transitions and Multiphase Systems 606 $aMaterials Characterization Technique 606 $aQuantum Fluids and Solids 615 0$aMagnetism. 615 0$aSpectrum analysis. 615 0$aPhotonics. 615 0$aCondensed matter. 615 0$aMaterials$xAnalysis. 615 0$aQuantum statistics. 615 14$aMagnetism. 615 24$aSpectroscopy. 615 24$aUltrafast Photonics. 615 24$aPhase Transitions and Multiphase Systems. 615 24$aMaterials Characterization Technique. 615 24$aQuantum Fluids and Solids. 676 $a538 700 $aIlyas$b Batyr$01853157 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911034946803321 996 $aCoherent Terahertz Control and Ultrafast Spectroscopy of Layered Antiferromagnets$94449205 997 $aUNINA
