Impact of next-nearest-neighbor hopping on ferromagnetism in diluted magnetic semiconductors

Autor: Subrat K. Das, Sourav Chakraborty, Kalpataru Pradhan

Publikováno v: Physical Review B. 102

Being a wide band gap system GaMnN attracted considerable interest after the discovery of highest reported ferromagnetic transition temperature $T_C$ $\sim$ 940 K among all diluted magnetic semiconductors. Later it become a debate due to the observat

Autor: Pankaj Malhotra, Velu Nair, Uday Yanamandra, Neelam Varma, Sushma Yanamandra, Subrat K Das, Subhash Varma, Angella Ayekappam, V. K. Lalitha Kumari, Suman Kumar, Srinivas A. Bhattachar

Publikováno v: Indian Journal of Hematology and Blood Transfusion. 34:731-738

Hematological adaptations to high altitude (HA) are long studied but are focused either on lowlanders visiting HA or native highlanders from Andes and Tibet. The literature on native highlanders from the Indian subcontinent or paediatric highlanders

Bedside Ultrasonography as an Alternative to Computed Tomography Scan for the Measurement of Optic Nerve Sheath Diameter

Autor: Sushma Yanamandra, Amul Gupta, Sagarika Patyal, Velu Nair, Subrat K Das, Uday Yanamandra

Journal of Neurosciences in Rural Practice

Background: Optic nerve sheath diameter (ONSD) as measured by optic nerve sheath ultrasonography (ONSU) is used as a surrogate marker of intracranial pressure (ICP), especially in resource-limited settings. There is a growing interest in the use of O

Comparison of Optic Nerve Sheath Diameter between both eyes: A Bedside Ultrasonography Approach

Autor: Uday Yanamandra, Srinivasa Bhattachar, R.S. Grewal, Velu Nair, Sushma Yanamandra, Sagarika Patyal, Subrat K Das, Amul Gupta

Publikováno v: Indian Journal of Critical Care Medicine : Peer-reviewed, Official Publication of Indian Society of Critical Care Medicine

Context: Optic nerve sheath diameter (ONSD) has long been accepted as a reliable proxy of intracranial pressure especially in critical care and bedside settings. The present consensus is to measure ONSD in both eyes and take average value, which is c

Erythropoietin and ferritin response in native highlanders aged 4-19 years from the Leh-Ladakh region of India

Autor: Velu Nair, Pankaj Malhotra, Sushma Yanamadra, Suman Kumar, Reena Das, Harikishan Senee, Srinivas A. Bhattachar, Subhash Varma, Uday Yanamandra, Subrat K Das, Neelam Varma

Publikováno v: British journal of haematology. 184(2)

The pivotal role of erythropoietin (EPO) in hypoxic adaptation has led to various studies assessing the EPO and ferritin response in native highlanders from Andes and Tibet. We assessed the relationship between EPO, haemoglobin and ferritin in 335 na

A new route to enhance the ferromagnetic transition temperature in diluted magnetic semiconductors

Autor: Subrat K. Das, Kalpataru Pradhan

Publikováno v: Scientific Reports
Scientific Reports, Vol 7, Iss 1, Pp 1-6 (2017)

We investigate the magnetic and the transport properties of diluted magnetic semiconductors using a spin-fermion Monte-Carlo method on a 3D lattice in the intermediate coupling regime. The ferromagnetic transition temperature $T_c$ shows an optimizat

Magnon spectrum in the domain ferromagnetic state of antisite-disordered double perovskites

Autor: Subrat K. Das, Pinaki Majumdar, Viveka Nand Singh

Publikováno v: Physical Review B. 88

In their ideal structure, double perovskites like Sr_2FeMoO_6 have alternating Fe and Mo along each cubic axes, and a homogeneous ferromagnetic metallic ground state. Imperfect annealing leads to the formation of structural domains. The moments on mi
