The only doubly magic region above 7828Ni accessible for detailed spectroscopic studies on the neutron rich side of nuclear landscape is 13250Sn region. High spin isomers in these nuclei have very often a rather pure single particle configuration and therefore good candidates to study details of the nuclear M1 and E2 properties. Shell model calculations can reproduce most of the high spin features of the nuclei in this mass region, but still some discrepancies remain. The g-factor measurements are therefore necessary to pinpoint the current faults in shell-model descriptions. Present measurement is the first such attempt to measure the g-factors of high spin isomers in the nuclei of the doubly magic 132Sn region, produced via relativistic energy projectile fragmentation of 136Xe at 700 MeV/A. A good degree of alignment (~ 12 %) obtained in this reaction indicates a major success of the campaign as now more neutron rich nuclei are opened for such studies.

A brief introduction will be given on magnetism in nanoscale systems and how size and shape affect magnetic behaviour. The importance of ion beams in the area of nanoscale magnetism will be illustrated with demonstration of dual roles of ion irradiation, namely, transformation of nonmagnetic materials into magnetic materials and vice versa. In the light of the observed phenomena, future developments in the area of nanotechnology, such as ultrahigh density magnetic storage devices, single-electron spin-valve transistors etc. will be discussed. Some nanoscale structures that can be fabricated using ion beams will offer the possibility of exploring new scientific aspects in these structures
