Single-Molecule magnets (SMMs) are molecular nanoscale materials continue to be at the
limelight of chemistry and material science in recent times due to their interesting framework and
prospective applications in various fields of fundamental and applied research such as
nanomagnetism, spintronics, quantum physics and quantum computation. As a result of its intrinsic
intramolecular behaviour, capable of increasing storage density eventually leads to miniaturization of
memory storage devices.1,2 It becomes possible due to its slow relaxation of magnetization between
the spin-up and spin-down states at zero field. Large number of such 3d, 4f and mixed 3d-4f complexes
received greater attention in this decade, because of exhibiting large energy (Ueff) for spin reversal
due to sufficient magnetic anisotropy. The family of poly nuclear first-row transition metal clusters
comprise the largest number of SMMs reported to date.2,3 After its dominated the field for the past
two decades, now single ion magnets are in trending due to their true axial anisotropy.
In addition, this kind of compounds has interdisciplinary covering a wide range of application
extend to multiferroic technologies. In multiferroic material, atleast two order states such as
magnetic, electric and piezo-electric phases coexist. They find their usage including data storage
recording technologies, energy harvesting and photo-voltaic technologies.4 In addition to synthetic
strategy, magnetic property and evolution of SMMs, the related current work will be presented in the
seminar.
