Abstract

We study bubble domain wall dynamics using micromagnetic simulations in perpendicularly magnetized ultra-thin films with disorder and Dzyaloshinskii-Moriya interaction. Disorder is incorporated into the material as grains with randomly distributed sizes and varying exchange constant at the edges. As expected, magnetic bubbles expand asymmetrically along the axis of the in-plane field under the simultaneous application of out-of-plane and in-plane fields. Remarkably, the shape of the bubble has a ripple-like part which causes a kink-like (steep decrease) feature in the velocity versus in-plane field curve. We show that these ripples originate due to the nucleation and interaction of vertical Bloch lines. Furthermore, we show that the Dzyaloshinskii-Moriya interaction field is not constant but rather depends on the in-plane field. We also extend the collective coordinate model for domain wall motion to a magnetic bubble and compare it with the results of micromagnetic simulations., Comment: To be published on J.

26. PROBLEMS OF ASSAMESE SPEAKERS LEARNING MANIPURI.

Author

Singh, H. Dolen, Sarma, Bhaskarjyoti, and Devi, N. Robita

Subjects
MANIPURI language, ASSAMESE language, PHONEMICS, TONE (Phonetics), PRONUNCIATION
Abstract

The article analyzes the problems of Assamese speakers learning Manipuri language at the North Eastern Regional Language Centre located in Guwahati, Assam in India. It specifically highlights the problems created by the differences between the segmental phonemes like vowels, diphthongs and consonants, and supra-segmental phonemes, particularly the tone. It explores the orthographic systems of both Manipuri and Assamese languages to analyze the pronunciation systems of Manipuri and Assamese.
