Discussion Overview

The discussion centers around the molecular structure of Nd2Fe14B, particularly its crystallography and the connections between its atoms. Participants explore the relevance of this information in the context of aerospace studies and applications in nanomotors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant inquires about the molecular structure of Nd2Fe14B and how its atoms connect.
  • Another participant provides a link to a visual representation of the crystal structure but questions its educational value.
  • A different participant describes the NdFeB structure as a complex layered structure based on the SmCo5-type hexagonal unit.
  • One participant expresses curiosity about the relevance of this information to aerospace studies and shares their experience with structure and magnetization measurements.
  • Another participant mentions additional images they found and seeks clarification on the differences between iron isotopes, indicating a need for this information for a final paper on nanomotors.
  • This participant also discusses their intention to compare theoretical and experimental values of magnetic moments for Nd2Fe14B, mentioning their modeling efforts.

Areas of Agreement / Disagreement

Participants express varying levels of interest and expertise in the topic, with some sharing resources and others seeking clarification. There is no consensus on the educational value of the images shared, and the discussion remains open-ended regarding the specifics of the molecular structure and its implications.

Contextual Notes

Participants reference specific isotopes and their representations, but the discussion does not resolve the differences or implications of these isotopes. The relevance of the Nd2Fe14B structure to aerospace applications is also not fully explored.

Does anyone know how does this molecule looks like? (I study Aerospace, don't ask me why do i want to know :cry: )
How does those atomos connect with each other:
It's chemical formulae is:
[tex]Nd_2Fe_1_4B[/tex]
 
Chemistry news on Phys.org
That's not needed right know, I've found it... if you want to know how the crystal of [tex]Nd_2Fe_1_4B[/tex] looks like just chek

You really don't learn anything from that picture.

The NdFeB structure is a complex layered structure based on repetitions of the SmCo5-type hexagonal unit.

I'm not supposed to ask you why...but I'm really curious why an aerospace major would need information of the crystallography of rare earth-transition metal intermetallic based permanent magnet compounds.

I've worked a little with some of these(mostly structure and magnetization measurements)...that's why I'm curious.
 
Thank you and by the way...

That wasn't the only picture I've found... I've got other that is more explicit than the one I've pasted the link (that was just for people who didn't need to know how it looked like as much as i did)... but I'm still trying to figure out what is the diference between [tex]Fe[/tex] isotopes symbolized by a full, blank, left side half full, right side half full and beyond...
What you told about the SmCo5-type hexagonal unit was a nice thing for me because i will be able to go further faster...
The reason I'm needing it it's because I'm doing a final paper about a nanomotor and i need to compare the teorethical values of magnetic moment of the [tex]Nd_2Fe_1_4B[/tex] with the experimental ones (after some scaling laws). So I will model it to study in a program (3, to tell you the truth...). I could ask my professor but he only returns to school on wednesday... like everyone else (it's portuguese republic day on tuesday...)
